GftK’s vdw 850 jointing mortar was selected for a sensitive project in Hitchin, Hertfordshire.  The old Market square project presented various challenges to dealing with the 750 sq. meter area of time worn granite and basalt setts.  Weather and disruption of business were among the many. Re-jointing was specified over re-laying and Vdw 850 was selected over several possible materials.  Gftk’s vdw 850, is the product for light traffic and sidewalks.  This has a medium permeability rate of 2 quarts / min/ 10 sf at 20% joints. Its compressive strength is 3,625 psi at 20% joints. (High performance for medium traffic)
Thanks to Tony McCormack of the and NCC Streetscapes, this video shows the preparation and techniques in rejointing an existing small format streetscape. The product is GftK’s vdw 850 self compacting epoxy resin jointing mortar. The paving contractor was RPB Ltd. Of Letchworth
